Parameterization via PROFIdrive data record 47
Operating Behavior (PROFINET IO)
Example for writ-
ing a parameter
via PROFIdrive The following tables show an example of the structure of the WRITE and READ services
for the remanent writing of the internal setpoint n11 of a MOVIDRIVE
®
B with SBus ad-
dress 1 that is connected to DHR41B via the CAN 1 system bus (see section 'Example
for writing a parameter via MOVILINK
®
' on page 111). The PROFIdrive Change para-
meter service is used for this purpose.
Send 'WRITE parameter' request
The following table shows the PROFINET header of the WRITE request with parameter
request.
The following table shows the WRITE.req user data for the PROFINET service "Change
Parameter".
After sending this WRITE.request, the WRITE.response is received. If there is no status
conflict in processing the parameter channel, a positive WRITE.response occurs.
Otherwise, the status fault is listed in Error_code_1.
